摘要

Abstract

In order to synthesize new polyamide (PA)

and copolyamides (CoPA)

7a−7d

a new-type of dicarboxylic acid containing triazine ring was successfully synthesized from 2

4-dichloro-6-methoxy-s-triazine 1 and 4-aminobenzoic acid. New polyamide

containing triazine moiety was prepared from 4

4′-(6-methoxy-1

5-triazine-2

4-diyl)bis(azanediyl)dibenzoic acid

and 4

4′-diaminodiphenylether by direct polycondensation reaction. Then new series thermally stable copolyamides

7a−7d

with high solubility in common organic solvents were synthesized from the direct polycondensation reaction of diacid

as a first monomer

aliphatic-aromatic diacids

6a−6d

as second diacids and 4

4′-diaminodiphenylether. All of the above polymers were fully characterized by

H-NMR and FTIR spectroscopy

elemental analysis (CHN)

inherent viscosity

solubility tests

gel permeation chromatography (GPC)

differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). The resulted CoPAs

7a−7d

have shown good inherent viscosities

solubility and thermal properties.
